  • the electronic cigarette may comprise two or more than two housings, so that the atomizer 30 , the sensor 3 , the control board 2 and the battery 1 may be received in different housings.
  • the main body 8 comprises a first housing and a second housing connected with the first housing.
  • the atomizer 30 and the sensor 3 are received in the first housing.
  • the control board 2 and the battery 1 are received in the second housing.
  • the electronic cigarette further comprises a switch 31 .
  • the switch 31 can be a mechanical switch as shown in FIG. 14 or a touch pad, as long as the switch 31 can trigger the atomizer 30 to work to generate smoke.
  • the user can trigger the atomizer 30 through the switch 31 or the sensor 3 .
  • the user can trigger the atomizer 30 through the cooperation of the switch 31 and the sensor 3 .
  • the atomizer 30 of this embodiment comprises a first airflow passage 50 and a second airflow passage 40 corresponding to the space of the sensor 3 .
  • the main body 8 of the electronic cigarette defines a first air inlet 81 in fluid communication with the first airflow passage 50 and a second air inlet 17 in fluid communication with the second airflow passage 40 .
  • the second air inlet 17 may be a gap between the atomizer 30 and the main body 8 .
  • the first airflow passage 50 and the second airflow passage 40 are isolated from each other by the partition member.
  • the atomizer 30 of this embodiment further comprises an atomizer head 11 and a venting unit 20 .
  • the atomizer head 11 is disposed at one end of the venting unit 20 .
  • the venting unit 20 comprises an inner air pipe 6 and an outer air pipe 7 .
  • the inner air pipe 6 is disposed inside the outer air pipe 7 .
  • the gap between the inner air pipe 6 and the outer air pipe 7 forms as an air inlet passage 52

  • the atomizer 30 further comprises a liquid storage sleeve 9 received in the main body 8 . Both the atomizer head 11 and the venting unit 20 are received in the liquid storage sleeve 9 . The space between the main body 8 and the liquid storage sleeve 9 forms as the second airflow passage 40 .
  • the first airflow passage 50 and the second airflow passage 40 are isolated from each other by the liquid storage sleeve 9 . That is, the liquid storage sleeve 9 acts as the partition member of the atomizer 30 .
  • the liquid storage sleeve 9 and the partition member 41 together form as a air flow passage separator for the electronic cigarette.
  • the atomizer head 11 includes an atomizing tube 19 , a heating element 12 , an atomizing base 13 , and a first contact member 14 .
  • the heating element 12 , the atomizing base 13 and the first contact member 14 are disposed in the atomizing tube 19 .
  • the heating element 12 is located above the atomizing base 13 .
  • the atomizing tube 19 is provided with an atomizing outlet 192 at one end thereof.
  • the atomizing base 13 is disposed at the other end of the atomizing tube 19 opposite to the atomizing outlet 192 .
  • the first contact member 14 is disposed at a bottom end of the atomizing base 13 .
  • the first airflow passage 50 and the second airflow passage 40 are isolated from each other by the partition member.
  • the second airflow passage 40 in which the sensor 3 is disposed, is isolated from the first airflow passage 50 by the partition member, such that the airflows in the two airflow passages are not mixed before being inhaled by the user. That is, the smoke will not flow through the second airflow passage 40 . Therefore, even if the smoke cools down, its influence to the sensitivity of the sensor 3 is greatly reduced. Accordingly, the sensor 3 can sensitively control the battery 1 to energize or not. As a result, the smoking experience for the user is improved.
